305-034-521-503

Edgeboard Connectors Overview

The EDAC Inc. 305-034-521-503 is a dual-edge female card edge connector from the 305 Series, designed for panel and through-hole mounting. It features 34 positions with a 0.156-inch (3.96mm) pitch across two rows of seven contacts each. The connector utilizes gold-plated half-cylinder terminals on a green thermoplastic polyester insulator. It accommodates card thicknesses between 0.054 and 0.070 inches and operates within a temperature range of -40°C to 105°C.
